        Spray foam under steps??? Sign In/Join 
        posted
        At the back of my house I have two 4'-5' long concrete steps. There is a huge gap below the top step and behind the bottom step, it extends the entire length of the steps. So far, I've filled in the gap with stone from the left and right but it's hard to get the stone in the middle area of the steps and basically there are quite a few gaps that will not get filled. My intention was to finish the job with concrete by "throwing it in from both sides and having a smooth finish.

        Could I spray foam in order to fill in the various gaps and then finish the sides with concrete?

        You could, but it wouldn't do anything to help.

        Expandable foam will deteriorate under outdoor exposure conditions. Instead of foam, mix up a pourable mortar mix. Keep it thin enough so that it can work it's way inside the cracks and gaps.

        The only problem is I have to get the mortar in from the sides. Any ways to fill the voids other than trying to "throw" it in?

        you need a mortar bag. This is a cone-shaped canvas bag with a metal tip about 1/4 inch in diameter. Put the mortar mix into the bag and squeeze the mix out the tip.

        You could use this...
        Just need a regular torch like for soldering. The stix melt and seal the crack.
